In a machine of this character it IS usual to employ comparatively smallfront wheels to provide a bed low down to facilitate easy loading. Asthe machine must also turn very close, the front wheels in turning, runpartly under the bed, which necessitates that the axle guides project asuflicient distance downward from the bed and hold the axle that thewheels can turn close without coming in contact with the bed,necessitating relative long axle guides. As the front axle is subject tosevere forward and backward jars, as the machine travels over unevenground and when the small front wheels hit obstructions or drop intofurrows or other depressions, it is essential that these guides, whichhold the axle in position, must be extremely strong and non-yielding inorder that this purpose ma be accomplished.

he bed of the vehicle is shown in Fig. 2

and consists of longitudinally-extending sills 1n the form of L-beams 1,connected by angle iron cross-sills 2, and having secured to the outerside of the vertical web thereof uprights 3 of angle-iron to which areconnected wooden sides 4. The boards 5 forming the bottom of the bed arelaid upon the crosss1lls 2 and secured thereto in any suitable way. Thetwo front members 3 on each side of the bed project below the side wallsor beams 1, bein bent toward each other as indlcated at 3 1n Fig. 3 andthence projected downwardly in parallel relation, as indicated at 3 soas to form guides for the axle to be descnbed. For the purpose ofstiffening these guide members the portions 3 have connected therewith atriangular-shaped plate 6 and the lower ends of the portions 3 areconnected by a bar 7 Thefront axle is preferably formed of twoangle-lron members 8, the edges of the horizontal and vertical webs ofwhich are placed together so as to form a hollow structure which has acentral filler member 9, this filler member and the two angle irons 8being connected together at a midway point by a pair of r1vets 10, asshown in Figs. 1, 2 and 4. Each of the ends of the axle projects throughthe corresponding guides 3 and secured to each end of the axle is aU-shaped plate 11, the vertical sides of which embrace the sides of theaxle members so as to cooperate with the guide members 3 to guide theaxle. The sides of the U-shaped plate at the points where they embracethe axle are extended, as indicated at 11, and are secured to the axlemember by one of the rivets 17 hereinafter referred to and also by anadditional rivet 12, as shown in Fi 5.

Each of the s eeve bearings 13 for the vertical portion 14-. of the axlespindle 15 has an integrally formed hollow shank 16, substantiallysquare in cross-section, which is placed in the adjacent end of the axleand rigidly connected therewith by rivets 17 which pass through thevertical webs of the two axle members. 8 so as to further stiffen theaxle structure and provide for rigidly securing the bearing sleevethereto. A sleeve 18 at the juncture of the vertical and horizontalportions of each spindle is keyed to the spindle by a pin, shown indotted lines at 19 in Fig. 5, and this sleeve has oppositely projectingears 20 to which are secured by rivets 21 the steering arm 22. The upperend of bearing sleeve 13 is closed by a cap 23 which is se-. cured tothe upper end of the spindle by the pin 24 so as to turn therewith, thecap being provided with means in the usual way for insertion oflubricant. The sleeve 18 not only acts as a means for attachment of thesteering arm but also serves to sup ort the bearing sleeve 13 and theweight 0 the vehicle im osed thereon through the axle.

From igs. 1, 2 and 5 it will be seen that the bearing sleeves 13 and thevertical portions of the axle spindles are inclined inwardly toward thebed from bottom to top. Further, it will be seen from Figs. 1 and 3 thateach of the bearing sleeves and vertical portions of the axle spindlesare inclined rearwardly from the bottom to the top. As a result of theseinclinations, when the front wheels are turned, the inner wheel willlean outwardly, while the outer wheel will re main perpendicular. Thisis due to the fact that with the inner wheel the two inclinations coacttogether to tilt the horizontal portion of the spindle downwardly, whilewlth the outer wheel the two inclinations offset each other to cause thehorizontal portion of the spindle to remain horizontal. As a result ofthis arrangement the'inner wheel, in turning, will clear the guidepieces 3, and in this connection it should be explained that in practiceit is the inner wheel only that needs to be tilted to avoid striking theguide pieces, hence this arrangement provides for the tilting of theinner wheel but not of the outer wheel.

A substantially til-shaped bolster 25 of an le iron has its horizontaland vertical webs riveted to the webs of one of the angle iron sills 2by the rivets 26 and has its central portion resting upon the top of thecentral portion of the axle. Secured to the vertical web of the bolsterby rivets 27 is a vertical web of a bent up plate 28, the horizontal webof which projects forwardly and is ofiset upwardly as indicated at 28.Secured to the forward side of the axle by rivets 10 is a U-shapedmember 29. The horizontal webs of this U-shaped member receive a pivotbolt 30 the head 30' of which is disposed between the upperhorizontalportion of'the member 29 and the ofiset portion 28; the bolthaving an extension 30" which extends loosely throu h the a erture inthe part 28, thus holdm the olster against endwise movement on t e axleand also holding the bolster in alignment with the axle. Pivoted on thisbolt is a sleeve 31 provided with a renewable bushing 32", which acts asa spacer. The sleeve 31 has on its forward side an integrally-formedtransversely-extending boss 31' provided with a transverselyarrangedopening 32 to receive a bolt 33 upon which is secured as rigidly aspossible the vertical webs of a pair-0f angle iron draft members 34which extend forwardly and point slightly back of the U-shaped draftmembers are apertured to receive a pin 37, one end of which has a head38 and the other adapted to receive a cotter pin 39. The tongue 40 isprovided with wear plates 45 at its sides and is inserted'between themembers 34 and is apertured to receive the pin 37 so that the tongue isconnected to the members 34 on a horizontal pivot, the members 34 beingin turn rigidly connected to the sleeve 31, which sleeve is connected tothe axle and bolster on a vertical pivot. This arrangement permits thetongue to swing vertically on the pin 37 and laterally by reason of thepivot 30.

- The steering arms 22 are connected with the draft members 34 throughthe links 41. The outer end of each of these links isformed with an eyeto receive a bushing 42 (Fig. 3) throughwhich extends a bolt 43 carriedby the arm 22, the free end of the arm being bent back in parallelspaced relation with the main portion thereol so as tdreceive the end ofthe link 41. The inner end of each of the links 41 is formed with an eye44 to receive a hardened pin 46 carried by a bracket 47 which is rivetedto the horizontal plates of the draft appliance members 34 as shown inFi 9. The upper end of the pin has a reduce neck 46 which passes throughan aperture in the bracket and is riveted down as shown in Fig. 9, thepin being renewable as occasion demands. The bracket 47 has endextensions 47, curved slightly in a rearward direction, which extensionsact as stops which contact with the axle member 8 to prevent turning tooclose.

In Fig. 10 the axle guide members are in the form of two parallel spaceda art angle bars 48 braced at their upper ends y a late 49 and connectedat their lower ends y a cross-bar 50, the bars and plate being rivetedor otherwise secured to the beam 1. In Fig. 11 are shown the sameparallel, spaced-apart angle members 48 connected at their lower ends bythe cross-bar 50, but instead of the plate 49 they are braced by bracerods 51 connected respectively to the guide members 48 to the beam 1 andan additional cross-bar 52 being provided. In Fi 12 the guide membersare in the form 0 an inverted U- shaped structure 53, which structurehas its 56 braces the upper ends of the members. In Fig. 16 there isshown a modification in the axle construction in which two channels 57are employed instead of the angle irons 8 shown in Fig. 4;. The fillermember indicated at 58 is also somewhat modified over the member 9 shownin Fig. 4. In Figs. 14 and 15 there is shown the same form of guidemembers as illustrated in F ig. 3, but the portions 3 and 3 of the rearguide is shown reinforced with an additional angle iron 3 placed on therear side thereof with the plate 6 between the same.

By the arrangement of axle guides described, in which a pair of guidesis provided for each end of the axle, the upper portions of which arerigidly connected to the longitudinal metal beams of the body as well asto the body, and which have their lower portions firmly braced by theupper cross plate 6 and lower tie rod 7, it will be seen that the axlewill not only be guided in its up and down movements and be limited insuch movements, but that provision is made for holding the axle inposition when the groundwheels swing partly under the bed in turning;this arrangement furnishing axle guides which will resist all shocks andjars which are brought upon the axle due to uneven travel of the machineand also to shocks which are brought upon the axle when the wheelsstrike boulders or other obstructions.

Having thus described my invention, I claim:

In a machine of the character described, a body having a fixed bolster,a metal axle supporting the central portion of said bolster for limitedrocking movement, guides embracing the ends of the axle, there being onepair of said guides at each side of the machine and comprising metalstrips bent to form a pair of spaced parallel lower portions, divergentmiddle portions, and upper portions, the upper portions being rigidlysecured to the sides of the body, a bar connecting the lower ends of theparallel portions close to the under side of the axle to limit rockingmovement of the axle, a plate rigidly connecting the divergent portionsto stiffen and brace the guides and hold them in proper spacing to eachother, and a connection between the axle and the central portion of thebloster which prevents lateral movement of the bolster with respect tothe axle but permits limited rocking movement of the bolster on theaxle.

In testimony whereof, I have hereunto set my hand this 11th day ofMarch, 1923.
